Jerking limbs during sleep, often described as sudden twitches or involuntary movements, are fairly common. These episodes—sometimes called sleep myoclonus or periodic limb movements—can disrupt sleep quality, leave you feeling unrested, and even disturb a bed partner. While occasional twitching is usually harmless, frequent episodes can impact energy, focus, and overall wellbeing.
In addition to practicing good sleep hygiene, natural supplements may provide gentle support. Certain nutrients help regulate muscle function, calm the nervous system, and promote more stable sleep patterns, which may reduce jerking or twitching during rest.
Here are two evidence-based supplements that may help.
Magnesium
Magnesium is one of the most important minerals for muscle relaxation and nervous system health. Low magnesium levels are often linked to muscle cramps, twitching, and restless sleep. Supplementing with magnesium can help calm muscle activity, reduce nighttime limb jerks, and improve overall sleep quality.
- Mechanism of action: Supports nerve and muscle relaxation to reduce nighttime twitching
- Dosage or usage tip: 200–400 mg daily, preferably taken in the evening before bed

Vitamin B12
Vitamin B12 plays a crucial role in nervous system function and red blood cell production. Deficiency in B12 has been linked to neurological issues, including muscle spasms and restless movements during sleep. Ensuring adequate B12 intake can support nerve health and may help lessen jerking limb episodes.
- Mechanism of action: Supports nervous system health and reduces neuromuscular disturbances
- Dosage or usage tip: 500–1,000 mcg daily, usually taken as a sublingual tablet or capsule

Summary
Jerking limbs during sleep can be frustrating, but nutritional support may help calm muscle activity and promote more restful nights. Magnesium helps relax muscles and nerves, while vitamin B12 supports healthy neurological function. Together, these supplements may contribute to steadier, more restorative sleep.
As always, it’s important to consult a healthcare professional before starting new supplements, especially if jerking limbs are frequent, severe, or accompanied by other health concerns.
